Sinse

A Sinse belongs to one of the lesser groups in school and usually has no friends. These are the people that you know sit in the back of the classroom plotting to kill everyone! They don't belong to any group, and they usually have a single style. They will wear the same clothes or something of the sort almost everyday. Sinse is an accronym for Single Individual Needing Social Experiece.

sinisa

Usually a priest especially a priest who enjoys helping the teens. He is very faithful and is good at praying over people. He likes to play basketball but is not good at it. He also loves spending all of the churches money on random things like bubble soccer. He also likes sacrifice such as sleeping without a bed. He enjoys staying in shape by running. Overall Sinisa is addicted to the church but also someone you can count on.

That guy just gave a great homily he must be a Sinisa
